Thanks Rip. The master cylinder was rebuilt at the same time by Power Brake Exchange and hopefully, they did it correctly. I agree with you on the bleeding and if I didn't have the K supplement I wouldn't have known different.

I don't know how old your m/c is or if it's been rebuilt, but if you can try another master cylinder. that may lead you to a resolution. Also, the bleeding procedure you describe seems strange to me, but if the manual says to do it that way, then I guess that is OK. Generally, bleeding of the brake system always started with the farthest wheel cylinder (RR) and then the next farthest (LR. RF and finally LF). I do not understand why a 64 K should be different.

Manual with a friend on the pedal? Gravity? Power bleeder? You have two circuits and need to rule out which one is the problem. I believe air is the problem and you want to know if its in the master or slave circuit.

Approx 2 years ago I was having leakage at the master cylinder and the brakes felt weak. I figured it was time for a rebuild. I removed both the master cylinder, the remote brake booster, and the slave cylinder and took them to Power Brake Exchange in Pittsburgh for rebuilding. They did find a broken spring in the remote booster and were able to replace it as well as the additional seals and such. They provided a test report and it showed the booster providing 300 psi? (I can not find the paperwork at this time but I believe that was the number.) I got everything back home and got back together. I also replaced the front wheel cylinders, shoes, and front hoses. Also, replace the vacuum line from the intake to the booster with the correct type of hose. I followed the service manual for the bleeding order of the system more than once. Here is the problem. I have brakes when the car first starts up. But after a couple of stops, the brake pedal starts bottoming out and the brakes do not hold. I was so frustrated and fed up that I just put the car away. In the meantime, I have become a cancer patient and I would really like to get this fixed and possibly enjoy the car this spring/ summer while I can.I have considered taking the car to the local Chrysler dealer whose ownership is into Mopar Muscle as I am not sure how much I can still do. Any thoughts or suggestions are appreciated as well as any shops in Ohio that may be able to work on this.
